To all whom it may concern.-

Be it known that I, HOBART B. IvEs,of New Haven, in the county of NewHaven, and in the State of Connecticut, have invented certain new anduseful Improvements in Adjustable Fasteners for Window-Beads; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,in which Figure 1 shows a perspective view of a portion of asash-frame,window-casing, and window-bead with my adjustable fastenerfor the bead; Fig.2,aview of a section on line wmof Fig. 1; Fig. 3,aplan view of my fastener in place in a window-bead; Fig. 4c, aview, onan enlarged scale, showing the bead-engaging part of my fastener in sideelevation without its .coacting screw; Fig. 5, a view of a section online y y of Fig. 4; Fig. 6, a view, on an enlarged scale, showing aperspective view of the beadengaging part of my fastener; and Fig. 7, a

The object of my invention is to provide an improved adjustable fastenerfor window-;

beads; and to this end my invention consists in the adjustable fastenerand in the beadengaging part thereof, as hereinafter specified, andpointed out in the claim.

My special object in making the present invention'is to make animprovement in that class of Window-bead fasteners in which there is athimble or cup-shaped piece to be inserted in a hole in the bead, havinga slotted table to be engaged by the head of a screw screwed into thecasing or part to which the bead is to be adjustably secured. With thispurpose in view I have devised the present fastener, with itsbead-engaging part, as hereinafter explained, especially intended andadapted to always fit and be properly seated in the opening for'it inthe bead, notwithstanding such variations in the beadholes as arise fromvariations in the action of difierent forms of boring-bits or in thenature of the wood of the bead, to be securely held against any rotationin the bead-hole in which it is seated, to offer no objectionableobstruction to the insertion or adjustment of walls of the fastener, andto have a strong thick slotted table for the engagement of theattaching-screw.

In the drawings, A designates a portion of a sash-bar, B a portion of awindow frame or casing to which the window-bead is to be fastened, and Ca portion of such bead.

C designates the hole in the bead C, and D designates the bead-engagingpart of my fastener seated in such hole and havingits slotted table D atits bottom, engaged by the head of the screw E, screwed into the frameor casing B, and having its shank passing through the slot d in table D.This slot extends in a direction transverse to the bead and is madelonger than the diameter of the screw-shank, so that the part D and thebead can be moved some distance toward and from the sashbar Aindependent of the screwshank. The body of the part D, being cupshaped,as shown, has its cavity above the table or bottom D made of greaterdiameter than the head of screw E to allow for the sidewise in-and-outadjustment of the bead and part D with reference to the screw-shank justabove referred to. The body of the part D is made tapering downward orinward toward the bottom or table end and has on its outer side thedownwardly or longitudinally extending ribs d d and on its upper orouter edge an outwardly-extending flange or. rib 01 to rest against theouter face of the bead when the fastener-body is seated in the hole C inthe bead. This flange or lip is made quite thin and preferably has itsunder side made flat, so that it can be seated squarely against the beadand will not stand out away from the latter, so as to catch dust orinterfere with the insertion or adjustment of a screen between the beadsof a window to which my fastener may be applied.

The ribs d d, of which there should be at least two, situated at or nearthe ends of a diametrical plane passing through the fastener-body atright angles to the slot d, are made tapering or diminishing in theamount of their projection beyond the outer side of the body of thefastener from their upper portion toward their lower ends. \Vhilc forthe best action in the even seating of the body in the hole in thesash-bead and the preventing of such body from rotation in such hole itis best that there should be at least two of the ribs (1 d, it ispossible, without departure from my invention, to have only one of suchribs, which by biting into the wood at the side of the hole in thesash-bead would prevent such objectionable rotation of the body of thefastener with reference to the sash-bead that might take place were theouter sides of such body made plain or unribbcd. Vhile two of these ribssituated as just above described can be used, I do not limit myself to'such number, but contemplate using more of them, as desired. In thedrawings four are shown, two being situated as above described and twomore being placed beyond opposite ends of the slot (1. W'hatever thenumber of ribs used may be, they are preferably all made tapering ordiminishing in height from their outer portion toward their inner endsin the manner hereinbefore described.

As shown in Figs. 2, 5, and 6, the slotted bottom or table D is madethicker than the side walls of the part D, so as to afford a good strongbearing for the head of the screw E, well adapted to stand the strainbroughtto bear upon such table when the screw is screwed in, so as tocause its head to bear upon the table strongly enough to hold thefastener and bead from outward or inward movement with reference to thesash-bar.

The side walls of the fastener can be made thinner, as there is nobending strain brought to bear upon them by the action of thefastening-screw. I make them, as shown, quite thin, so as to secure thegreatest possible room for side play of the part D and windowbead withreference to the screw E.

The ribs d d, which I make integral with the body of the fastener and ofsolid portions of the metal formed on the outside of the body withoutany corresponding grooves or offsets on the inside of the latter, serveas stiifeners to strengthen the walls of the body against inwardpressure the fastener is driven home in the hole prepared for it in thewindowbead.- Being made in one piece with the body D and with the lip orflange d it is clear that the ribs (1 d, forming rigid connectionsbetween the sides of the body and the lip beyond such sides and well outtoward its outer edge, are admirably adapted to stiffen and hold the lipor flange against any bending strain such as it is subjected to by itsengagement with the outer face of the head when the body D is drawninward in its receiving-hole in the head and when the screw is screwedinto the hole the head from sidewise movement by the engagement of thescrew-head with the outer or upper face of the slotted table D. Withthese ribs so connected with or formed in one piece with the body thelip or flange d can be made quite thin, so as to project but veryslightly above the surface of the head without any danger of its bendingor giving under any strain brought to bear upon it, as the strain of thescrew upon the table D tends to draw the body D inward in the head-hole.With the ribs (Z d, secured to the flange or lip, made tapering downwardorinward therefrom and V-shaped in cross-section they are adapted toafford the greatest possible strengthening of the flange, whileaffording the least amount of resistance to the seating of the body D inthe hole in the head, with its flange or lip d resting flatly againstthe face of the bead around the edge of the hole therein. The diameterof the hole as bored does not have to be increased because of theseribs, for the latter as the part D is seated in the bead-hole, beingnarrow and preferably sharp, find room for themselves in grooves whichthey make in the sides of the hole however hard the wood of the bead maybe. The ribs so seated in the wood around the hole in the bead will theneffectually prevent any chance of rotation of the part D in said hole asthe screw E is turned in one way or the other to release part D orsecure it and the head at any desired point of their adjustment withrelation to the sash window frame or casing and sash-bar.

\Vith both the body or part D of the fastener and the ribs on the outerside of the latter made tapering from the outer toward the inner end ofpart D it has been found that my improved fasteners can readily beproperly and securely seated in the window-beads even when there isconsiderable variation in such holes, such as may be caused by the useof different forms of boring-tools or of the same tool in differentwoods. In spite of such variations in the receiving-holes the part D ofmy fastener can always be readily seated, so that the lip or flange dwill be flat against the bead, and the ribs (1 (1 will so engage thewood around the hole as to effectually prevent any rotation of the partD to take its slot (Z out of a line transverse to the bead.

In making the part D of my fastener, as above described, and shown inthe drawings, I prefer to draw it from one piece of metal, firststamping a cup from a disk of metal by a suitable stamp and die. Thiscup I then draw by suitable dies, so as to leave the thick table orbottom D, and make the sides thinner by forcing up the metal to form thelip or flange d at the same time forming the ribs d d. The surplus metalis then cut off from the edges of the lip or flange, and the slot (1 iscut in the table or bottom D by any suitable die or tool.

Having thus described my invention, what I claim is- As an article ofmanufacture, a device for use in adjustable fasteners for window-beads,having a thick slotted table, thin sides and a lip or flange, said sidesbeing drawn up from the metal adjacent to the table to form with thetable a cup-shaped body with the lip or flange on its upper edge, suchtable being left spaces 3 substantially the normal thickness of the havehereunto set my hand this 3d day of Demetal, and said lip being formedof the metal cember, 1897. displaced in thinning the sides, such bottom,sides and lip being integral with each HOBART IVEb' 5 other,substantially as and for the purpose de- Witnesses:
